Wheel speed difference driven pump is as far away from racing as you can think... diffsonline for example sells E39 M5 40% lock LSD for a reasonable offer ...

This is something that will change the car's character
Out of ignorance, I normally wouldn't agree to invest in such an expensive mod so easily, but after having swapped my entire diff out (for other different reasons), I can attest to this being fact. My new upgraded unit helps put power down EXTREMELY well. I thought my car handled well to begin with, but with the new diff, it stuck like glue; even with 440RWHP!

Another option is Jim Blanton @ Performance Gearing. I'm huge on customer service, and PG blew me away with the seamless process. I told Jim that my car was a daily driver and I wanted minimal downtime. He worked with me to have my new diff shipped on time and within budget scope, as well as gave me a whole month's time if needed to return the core unit for some cost savings. Everything was done within 1 week. Can't really get much better than that!
